Network communication method and system, device, and storage medium

A network communication system, comprising a first network device in a first private network, a second network device in a second private network, and a gateway device coupling the first private network to the second private network, wherein the first network device, the second network device, and the gateway device are configured to perform a plurality of operations including:

• receiving, by the first network device, a first data packet transmitted from a terminal in the first private network to a target blockchain node in the second private network;
• acquiring, by the first network device, an actual network address of the target blockchain node, the actual network address being an intranet address of the target blockchain node in the second private network;
• generating, by the first network device, a second data packet according to the first data packet and the actual network address, the second data packet carrying the first data packet and the actual network address;
• and
• transmitting, by the first network device, the second data packet to a virtual network address of the second network device in the second private network, the virtual network address being used for the gateway device to forward a received data packet including the second data packet to the second network device.

A non-transitory computer-readable storage medium, storing at least one instruction, the instruction being loaded and executed by a network communication system comprising a first network device in a first private network, a second network device in a second private network, and a gateway device coupling the first private network to the second private network, wherein the first network device, the second network device, and the gateway device are configured to perform a plurality of operations including:

• receiving, by the first network device, a first data packet transmitted from a terminal in the first private network to a target blockchain node in the second private network;
• acquiring, by the first network device, an actual network address of the target blockchain node, the actual network address being an intranet address of the target blockchain node in the second private network;
• generating, by the first network device, a second data packet according to the first data packet and the actual network address, the second data packet carrying the first data packet and the actual network address;
• and
• transmitting, by the first network device, the second data packet to a virtual network address of the second network device in the second private network, the virtual network address being used for the gateway device to forward a received data packet including the second data packet to the second network device.
